Abstract
An apparatus and method for piercing a metering disc from a workpiece of a fuel injector. The metering disc includes first and second surfaces that extend substantially parallel to a base plane. The first and second surfaces are spaced along a longitudinal axis that extends orthogonal with respect to the base plane. The apparatus includes a piercing tool that extends along a tool axis, a planar coordinate positioning mechanism, and a spherical coordinate positioning mechanism. The piercing tool is adapted to penetrate the workpiece. The planar coordinate positioning mechanism displaces parallel to the longitudinal axis of the piercing tool relative to the workpiece. And the spherical coordinate positioning mechanism pivots about the tool axis relative at least one of three axes.
